[jira] [Commented] (HBASE-4160) HBase shell move and online may be unusable if region name or server includes binary-encoded data

["Jonathan Hsieh (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-4160?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13079048#comment-13079048 ] 

Jonathan Hsieh commented on HBASE-4160:
---------------------------------------

HBASE-4115 solves the case when signed negative hex bytes are input.  They seem to be processed differently with the two conversion functions.  'online' and 'move' will suffer the same problems.

Here's an example command at shell, and  byte array received by HMaster.assign(....)

before patch: assign "\xff\xfe" [-17, -65, -67, -17, -65, -67]
after patch: assign "\xff\xfe" [-1, -2]

before patch: assign "\x7f\x80" [127, -17, -65, -67]
after patch: assign "\x7f\x80" [127, -128]

This might be an encoding issue with o.a.h.hbase.utils.Bytes.toBytes.

> Similar to HBASE-4115, this entails a conversion of org.apache.hadoop.hbase.utils.Bytes.toBytes to a to_java_bytes call in the 'move' and 'online' call.
